Filters available in WPPizza Add Ingredients

wppizza_ingredients_filter_email_styles

The below filter will *only* apply to emails (as emails need style declarations to be added inline). For Print templates, use the css input in WPPizza->Templates->Print in conjunction with your browsers element inspector

@param: array
@return: array

add_filter('wppizza_ingredients_filter_email_styles', 'myprefix_ingredients_filter_email_styles');
function myprefix_ingredients_filter_email_styles($styles){
	/*  
	default styles passed on to $styles parameter are currently as follows (though might get tweaked in the future) 
		
	$styles = array();
	$styles['ingrinfo'] 	= 'white-space: initial; margin: 3px; line-height: 130%;' ;
	$styles['ingr_item'] 	= 'font-style: italic;' ;
	$styles['ingrinfo'] 	= 'white-space: initial; margin: 3px 3px 3px 20px; line-height: 130%; font-size:85%;' ;

	/* 

	if you want to - for example - increase the font for each ingredients in your emails to 
	120% instead of the default of 85%, you can do this

WordPress inbuilt ‘get_post_metadata’ filter

A snippet you could use to override the ‘half/half’ and/or ‘quarter’ options on a per size basis for any menu item.
I.e if you have a menu item with “small”, “medium”, “large” and “xxl” sizes and have enabled “whole”, “halfs” and “quarters” for this but do *not* want to have the “halfs” or “quarters” option available for the “small” size, you could do something like the below

@param: mixed
@param: int
@param: str
@return: mixed

/*
The below can be condensed somewhat , but for clarity 
we keep conditionals a bit more separate here in this example
*/
//Add the filter, using wordpress inbuilt 'get_post_metadata' filters
add_filter('get_post_metadata', 'myprefix_modify_wppizzaingredients_slices', 100, 3);
function myprefix_modify_wppizzaingredients_slices($metadata, $object_id, $meta_key){

	/*
	making sure we are only ever listening to *frontend* ajax requests here 
	(there are other way to do this too, but for simplicities sake...)
	*/
	if(!empty($_POST['action']) && $_POST['action'] === 'wppizza_ingredients_json' ){

		/* 
		the meta key used in the wppizza add ingredients plugin

			/*
